Turbulent and laminar flows in two dimensions: March 20 – April 21, 2017

Organized by: Gregory Falkovich and Alexander Zamolodchikov

Attendee List

Fluid mechanics in two dimensions has wide range of applications and possesses unique mathematical properties which are far from being fully explored and used. A landmark feature of turbulence in two dimensions is an inverse cascade, that is an appearance of large vortices and jets out of multi-scale random flow. It is the most significant and most surprising discovery in turbulence in the last fifty years. We still have no adequate conceptual framework for this counter-intuitive process of self-organization. Several inverse cascades demonstrate conformal invariance, found empirically and still having no theoretical explanation. After the inverse cascade reaches the system size, it creates a coherent flow sometimes called condensate. Interaction of turbulence and condensate is presently one of the most active fields of turbulence research. Apart from fundamental importance, inverse turbulence cascades and condensates are ubiquitous features of astrophysical, geophysical and industrial flows, from planet atmospheres to tokamak plasma.

On the other hand, even laminar and regular flows in two dimensions are of great interest ranging from microfluidics to emerging hydrodynamics of current flows in graphene. This latter subject requires the development of relativistic hydrodynamics.

The program is to be a place where turbulence theoreticians can meet field theorists and mathematicians to facilitate development of a common theoretical framework. In addition, representatives of plasma, solid-state, astro and geo-physics are welcome to participate and facilitate applications of the theory to different real-world phenomena.

This program is also hosting a workshop Fluid flows: from graphene to planet atmospheres: March 20-24, 2017.

The Organizer Gregory Falkovich will also be hosting a mini-course: Modern Fluid Mechanics: From viscous electronics in graphene to conformal invariance and anomalies in turbulence
